Novel medical optical lens

Abstract

The invention relates to the technical field of lenses for laser, and discloses a novel medical optical lens which is characterized in that a sliding groove is formed in one side of the lens, an edge groove is formed in the other side of the lens, the sliding groove corresponds to the edge groove in position, a light beam generates a diffraction phenomenon after entering the edge groove, and after passing through the interior of the lens, the light beam passes through the edge groove. Light beams are diverged by the sliding grooves, so that the light beams are distributed on a large surface, harmful high power density cannot be generated, and as the light rays are emitted from a larger scattering surface, the diffusion range is larger, and eye lenses cannot be focused on fine light spots, the retina and optic nerves cannot be damaged.

Description

Technical Field

[0001] The invention relates to the technical field of laser lenses, in particular to a new type of medical optical lens. Background Art

[0002] The laser emitted by the laser is directional light, and the light waves of the laser beam are highly consistent in space and time, that is, all light waves have the same phase, forming a consistent light wave front. This coherence enables the laser to produce a very narrow, concentrated and highly directional light beam.

[0003] The light of a conventional laser (almost parallel) can reach the lens of the eye even from a great distance. Since the energy of the laser beam is concentrated in a very small area, the laser has a high brightness and energy density. The energy of the laser is focused on the retina of the eye, which may cause serious damage such as burns or loss of vision. This risk is exacerbated, especially with high-power lasers or long-term exposure.

[0004] Therefore, we proposed a new type of medical optical lens to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a new type of medical optical lens to solve the problem that the laser beam hardly spreads as mentioned in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a new type of medical optical lens, comprising a lens, one side of the lens is provided with a sliding groove, the other side of the lens is provided with an rib groove, and the positions of the sliding groove and the rib groove correspond to each other.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The present invention discloses a novel medical optical lens. When a light beam enters a ridge groove, a diffraction phenomenon occurs. After passing through the interior of the lens, the light beam is diverged by the groove, so that the light beam is distributed over a large surface. Therefore, harmful high power density is not generated, and the light beam cannot be focused into a point, thereby protecting the eyes. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1 and Figure 2 A new type of medical optical lens includes a lens 1, a sliding groove 11 is opened on one side of the lens 1, and an rib groove 12 is opened on the other side of the lens 1, and the positions of the sliding groove 11 and the rib groove 12 correspond to each other, and the sliding groove 11 and the rib groove 12 are used to expand the direction of the laser beam.

[0014] In this embodiment, the laser beam is transformed through the scattering surfaces in the rib groove 12 and the sliding groove 11, thereby changing the direction of the beam and avoiding the beam from being parallel, so that the beam cannot be focused into a point and is completely harmless to the eyes.

[0015] Working principle: The light beam generates diffraction after entering the rib groove 12. After passing through the inside of the lens 1, the light beam is diverged by the groove 11, so that the light beam is distributed on a large surface, so no harmful high power density is generated. Since the light is emitted from a larger scattering surface and has a larger diffusion range, the eye lens cannot focus on a small light spot, so it will not cause damage to the retina and optic nerve.

[0017] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
